You can put this solution on YOUR website! Lets do this question by using algebra.
First, make the unknown things variables.
Make Mrs. kim "m" and her husband "h".
So, state the knowledge that u have so far.
m=h-4
m+h=62
Now, replace m with h-4
So, h-4+h=62
Simplify
h-4+h=62
2h-4=62
add both sides by 4
2h=66
divide both sides by 2
h=33
now, replace h with 33 to find out m
33-4=m
29=m
now u have the answer:
m=29
h=33
check:
29=33-4
29=29 CORRECT!!!
so, here is the answer once again:
m=29
h=33
